SOOKIE: That is a great lemon.
JACKSON: Try it, it’s a Meyer.
A Meyer lemon is not a true lemon. It’s a cross between a citron and a mandarin/pomelo hybrid. Hardy and easy to grow, Meyer lemons have a sweeter flavour than lemons.
Native to China, it was introduced to the US in 1908 by agricultural explorer, Frank Meyer. It became popular as a food item in the 1970s as part of the rise in Californian Cuisine, and was later championed by Connecticut-based Martha Stewart.
Meyer lemons need a greenhouse in cooler climates like Connecticut, and generally have mature fruit in winter. Jackson already has one fruiting in early September, no doubt because it’s from a greenhouse.
